Zheng Quan Shi Bao Wang·2025-08-26 08:15Core Viewpoint - The launch of the "Tongjun" and "Junguang" dredgers marks a significant advancement in China's dredging capabilities, filling a gap in the market for ultra-large dredgers with a capacity of 35,000 cubic meters, and enhancing China's position in the international high-end dredging market [1][4]. Group 1: Vessel Specifications and Capabilities - The "Tongjun" and "Junguang" dredgers have a design length of 198 meters, a width of 38.5 meters, a depth of 18 meters, and a maximum dredging depth of 120 meters, making them the largest in Asia [2][3]. - These vessels can operate in conditions of up to 8-level wind and have a maximum blowing distance of 12 kilometers, which meets the demands of long-distance dredging projects [3][4]. - The dredgers are equipped with a high-pressure water jet system capable of exerting a force equivalent to that of a 5-ton elephant on a palm, significantly enhancing their ability to excavate hard soil [3]. Group 2: Technological Innovations - The dredgers feature a domestically developed intelligent dredging system that combines artificial intelligence with dredging mechanisms, allowing for automated operation and adaptability to various soil types and seabed conditions [3]. - The vessels have a domestic equipment localization rate of 95%, breaking the long-standing foreign monopoly on large dredger construction and intelligent dredging technology [2]. Group 3: Market Implications - The introduction of the "Tongjun" and "Junguang" dredgers is expected to boost China's competitiveness in the international dredging market, transitioning the country from an importer to a technology exporter in dredging equipment [4][5]. - The demand for infrastructure development in countries along the "Belt and Road" initiative presents significant market potential for these advanced dredging vessels, particularly in Southeast Asia, the Middle East, and Africa [5]. - The successful operation of the "Junyang 1" dredger, which has demonstrated high efficiency in deep-sea sand extraction, underscores the capabilities of Chinese dredging technology and sets a precedent for the new vessels [6].
